Abstract
Optically transparent, relatively high refractive index polymeric compositions and ophthalmic devices such as intraocular lenses and corneal inlays made therefrom are described herein. The preferred polymeric compositions are produced through the polymerization of one or more copolymers with one or more hydrophilic monomers and optionally one or more aromatic-based monomers, hydrophobic monomers or a combination thereof.
